booke23 - You get what you pays for. If you want someone else to guarantee separation / you don't trust yourself to look out then get an IR and always fly in Class A. If you want the freedom of F and G then stop complaining.
You're the sort who would insist a 40yr old gilder with NO electrics at all (in case this is not clear: no radio, GPS, torch, battery, ....) has a transponder so that it's not your fault when YOU cut them up.
